I think I get you now.  You're suggesting that we essentially
do what Dave has right now in the non-contending case, i.e.,
bypassing the qdisc so we get fully parallel processing until
one of the hardware queues seizes up.

At that point you'd stop all queues and make every packet go
through the software qdisc to ensure ordering.  This continues
until all queues have vacancies again.

If this is what you're suggesting, then I think that will offer
pretty much the same behaviour as what we've got, while still
offering at least some (perhaps even most, but that is debatable)
of the benefits of multi-queue.

At this point I don't think this is something that we need right
now, but it would be good to make sure that the architecture
allows such a thing to be implemented in future.

Cheers,
